Weak Passwords and Default Usernames

One of the oldest tricks in the hacker’s book is guessing credentials. If your WordPress site uses easy-to-guess usernames and passwords, you’re essentially leaving the front door unlocked. The most common culprit? The default “admin” username.

The “Admin” User Threat

When WordPress was first installed, many users would stick with “admin” as the administrator username. This provides hackers with half of the login equation immediately, making brute-force attacks significantly easier.

Creating Strong Passwords

A strong password is a combination of uppercase and lowercase letters, numbers, and symbols. It should be at least 12-16 characters long and unique to each account. Avoid using personal information, common words, or easily guessable patterns.

How to Fix It:

1. Change the “admin” Username:

   • If you still have “admin”: Create a new administrator user with a unique username (not “admin”, not your site name, not your real name). Log in as the new user, then delete the old “admin” user, ensuring you attribute its content to your new user.
   • Via phpMyAdmin (advanced): If you can’t access your admin area, you can change the username directly in the wp_users table (or whatever your prefix is) via Hostinger’s hPanel -> Databases -> phpMyAdmin. Be extremely careful with direct database edits.

2. Use Strong Passwords:

   • For existing users: Navigate to Users > All Users in your WordPress dashboard, edit each user, and click “Set New Password.”
   • For new users: Always generate strong, random passwords.
   • Hostinger’s Password Management: Hostinger provides robust security for your hPanel and FTP access. Ensure those passwords are equally strong and consider enabling 2FA for your Hostinger account itself.

Key Takeaway for Passwords

Neglecting WordPress Core, Theme, and Plugin Updates

Software is rarely perfect, and security vulnerabilities are often discovered after release. Developers then issue patches in the form of updates. Ignoring these updates is like ignoring a security bulletin for your house – you’re knowingly leaving a weak spot exposed.

The Patchwork of Vulnerabilities

Every component of your WordPress site – the core software, your chosen theme, and any plugins you install – can harbor security flaws. If even one component is outdated, your entire site is at risk. Attackers actively scan for sites running known vulnerable versions of software.

Why Updates Matter

• Security Patches: This is the primary reason. Updates fix known vulnerabilities that hackers could exploit.
• Bug Fixes: Improve stability and prevent errors.
• New Features & Performance: While not directly security-related, these improve user experience and site health.

How to Fix It:

1. Enable Automatic Updates:

   • WordPress has significantly improved its automatic update features. For minor core updates, they often happen automatically.
   • For themes and plugins, you can enable auto-updates via the WordPress dashboard (Dashboard > Updates or individually for themes/plugins).
   • Caveat: While convenient, automatic updates can sometimes break your site due to incompatibilities. Always have a recent backup before enabling them universally.

2. Regular Manual Updates:

   • Check for updates frequently (Dashboard > Updates).
   • Before updating: Always create a full backup of your website. Hostinger provides automatic daily/weekly backups, but a manual backup via hPanel (Files > Backups) or a plugin is also wise.
   • Test updates on a staging environment if possible (Hostinger offers a staging tool for WordPress).
   • Only use themes and plugins from reputable sources. Delete any inactive themes or plugins to reduce potential attack vectors.

Ignoring Hostinger’s Built-in Security Features

Hostinger isn’t just a platform; it’s an environment with its own set of security tools. Many users overlook or don’t fully utilize these powerful features that are already included in their hosting plan.

Hostinger’s Security Arsenal:

• Cloudflare Integration: Hostinger offers easy Cloudflare setup, which acts as a Web Application Firewall (WAF), filters malicious traffic, and provides DDoS protection.
• LiteSpeed Cache: Beyond speed, LiteSpeed includes security features to protect against certain attack types.
• Web Application Firewall (WAF): Hostinger’s WAF (often integrated with Cloudflare) actively monitors and filters HTTP traffic between your web application and the Internet.
• Automatic Backups: Most Hostinger plans include daily or weekly automatic backups, a crucial safety net.
• Malware Scanner: Hostinger provides a built-in malware scanner (Security > Malware Scanner in hPanel) to detect and remove malicious files.
• Free SSL Certificate: An SSL certificate encrypts data between your site and visitors, crucial for security and SEO. Hostinger provides free SSL via Let’s Encrypt.

How to Fix It:

1. Activate Cloudflare: Go to Advanced > Cloudflare in hPanel and follow the instructions to enable and configure it.
2. Ensure SSL is Active: Navigate to Security > SSL in hPanel. Make sure your free SSL is installed and active for your domain. If not, click “Install.”
3. Regularly Scan for Malware: Schedule and run malware scans through your hPanel. If any threats are found, follow Hostinger’s recommendations for removal.
4. Understand Your Backups: Familiarize yourself with how Hostinger’s automatic backups work and how to restore from them. Consider supplementing with a plugin-based backup solution for more granular control.

Improper File Permissions

File permissions control who can read, write, or execute files and folders on your server. Incorrect permissions can allow attackers to upload malicious files, modify your existing files, or even execute commands on your server.

Understanding File Permissions

Permissions are typically represented by a three-digit number (e.g., 755, 644).

• First digit: Owner permissions
• Second digit: Group permissions
• Third digit: Public permissions
• Numbers:

  • 4 (Read): Allows viewing the file/directory contents.
  • 2 (Write): Allows modifying the file/directory contents.
  • 1 (Execute): Allows running the file/accessing directory contents.
  • Sum these numbers for combined permissions (e.g., 7 = Read+Write+Execute).

Recommended Settings:

• Folders: 755 (owner can read, write, execute; group and public can read and execute).
• Files: 644 (owner can read and write; group and public can only read).
• wp-config.php: 640 or 600 (more restrictive, only the server owner can read/write).

How to Fix It:

1. Access File Manager: Log in to your Hostinger hPanel, then go to Files > File Manager.
2. Navigate to your WordPress Root: Typically public_html.
3. Change Permissions:

   • Right-click on a folder or file.
   • Select “Permissions.”
   • Enter the recommended numeric value (e.g., 755 for folders, 644 for files).
   • Check “Apply permissions to files and subdirectories” carefully for folders (only apply 755 to folders, then go back and apply 644 to files).
   • Use an FTP Client: For bulk changes, an FTP client like FileZilla is more efficient. Connect using your Hostinger FTP credentials (found in hPanel under Files > FTP Accounts).

Not Using a Dedicated WordPress Security Plugin

While Hostinger provides server-level security, a WordPress security plugin offers an extra layer of defense directly within your application, providing monitoring, firewall capabilities, and hardening features specific to WordPress.

Why You Need One

• Application-Level Firewall: Blocks malicious requests before they reach WordPress.
• Malware Scanning & Removal: Scans your WordPress files for malicious code.
• Brute-Force Protection: Limits login attempts.
• Security Hardening: Helps you implement best practices (e.g., disabling XML-RPC, changing database prefix).
• Activity Monitoring: Keeps a log of events on your site.

Popular Choices

• Wordfence Security: Comprehensive firewall and malware scanner.
• iThemes Security (formerly Better WP Security): Offers a wide range of hardening features.
• Sucuri Security: Cloud-based WAF and malware removal service.

How to Fix It:

1. Choose a Plugin: Research and select a reputable security plugin. For beginners, Wordfence (free version) or iThemes Security (free version) are excellent starting points.
2. Install and Configure:

   • Go to Plugins > Add New in your WordPress dashboard.
   • Search for your chosen plugin, install, and activate it.
   • Follow the plugin’s setup wizard to configure its settings. Pay attention to firewall rules, malware scanning schedules, and hardening options.

3. Regularly Monitor Reports: Check the plugin’s dashboard and email alerts for any security notifications.

Using the Default Database Prefix (wp_)

When you install WordPress, the default database table prefix is wp_. This is widely known, and it gives attackers a head start in crafting SQL injection attacks against your database. They know exactly which tables to target (e.g., wp_users, wp_posts).

The Risk

Knowing the table prefix simplifies attacks, making it easier for automated bots to target your database. While not the most critical vulnerability on its own, it’s an easy fix that adds an extra hurdle for potential attackers.

How to Fix It:

1. During Installation (Recommended):

   • When installing WordPress manually or via Hostinger’s auto-installer (if it provides the option), change the wp_ prefix to something unique (e.g., wp123_, mysite_).

2. Post-Installation (More Complex):

   • Backup! This is a database operation, so a full backup is absolutely essential.

   • Edit wp-config.php: Change the $table_prefix variable to your new prefix.

   • Update Database Tables: Access phpMyAdmin via Hostinger hPanel. You’ll need to run SQL queries to rename all existing tables and then update any serialized data within those tables that reference the old prefix. This step is prone to errors, so proceed with extreme caution or use a plugin designed for this purpose (e.g., iThemes Security Pro).

   • Example SQL (for renaming tables, after backing up and changing wp-config.php):
     sql
     RENAME TABLE wp_comments TO mynewprefix_comments;
     RENAME TABLE wp_commentmeta TO mynewprefix_commentmeta;
     — Repeat for all wp_ tables

   • Update Options Table: Update option_name in _options table where it uses the old prefix (e.g., wp_user_roles).

   • Update Usermeta Table: Update meta_key in _usermeta table where it uses the old prefix.

Exposing Sensitive Files (wp-config.php and .htaccess)

The wp-config.php file contains critical WordPress configuration details, including your database credentials. The .htaccess file controls server behavior, including redirects, caching, and security rules. Leaving these files exposed or improperly configured is a major security blunder.

Securing wp-config.php

This file is your site’s brain. If it falls into the wrong hands, an attacker gains full database access.

How to Fix It:

1. Restrict Permissions: As mentioned in the file permissions section, set wp-config.php permissions to 640 or 600.
2. Move wp-config.php: For an extra layer of security, you can move wp-config.php one directory above your WordPress root (public_html). WordPress is designed to look for it there if it’s not in the main directory. This means if your public_html directory is compromised, wp-config.php might remain safe.
3. Add Security Keys: Ensure your wp-config.php has unique “Salt Keys.” WordPress uses these to encrypt cookies and passwords. You can generate new ones from the official WordPress API and paste them into your file.

Hardening .htaccess

The .htaccess file can be used to implement various security measures.

How to Fix It:

1. Disable Directory Browsing: Prevents visitors from seeing the contents of directories without an index.php or index.html file.
   apache
   Options -Indexes

2. Prevent PHP Execution in Uploads: Prevents attackers from running malicious PHP scripts in your wp-content/uploads folder.
   apache
   <Files *.php>
   deny from all

3. Protect wp-config.php (via .htaccess):
   apache

   
   order allow,deny
   deny from all
   

4. Allow Access to wp-login.php Only from Specific IPs (Advanced):
   apache

   
   Order Deny,Allow
   Deny from all
   Allow from YOUR_IP_ADDRESS_HERE
   

   Replace YOUR_IP_ADDRESS_HERE with your actual static IP. Be extremely careful with this, as a wrong IP or dynamic IP can lock you out.

How to Edit: Use Hostinger’s File Manager (Files > File Manager) to edit .htaccess in your public_html directory. Always back up your .htaccess file before making changes.

Lack of Two-Factor Authentication (2FA)

Even the strongest password can be cracked or stolen. Two-Factor Authentication (2FA) adds an essential layer of security by requiring a second verification method beyond just your password, usually something you have (like your phone).

An Extra Layer of Defense

With 2FA, even if an attacker gets your username and password, they can’t log in without access to your second factor (e.g., a code from an authenticator app, an SMS code).

How to Fix It:

1. Enable 2FA for Hostinger Account: First and foremost, secure your hPanel access. Hostinger provides 2FA options within your account settings. This protects your entire hosting environment.
2. Implement 2FA for WordPress:

   • Plugins: Install a 2FA plugin for WordPress. Popular options include Wordfence Security (comes with 2FA), iThemes Security, or dedicated 2FA plugins like Two-Factor Authentication (by idealo) or WP 2FA.
   • Configuration: Follow the plugin’s instructions to set up 2FA for your WordPress admin users, typically involving scanning a QR code with an authenticator app (like Google Authenticator or Authy).

Leaving XML-RPC Enabled Unnecessarily

XML-RPC (xmlrpc.php) is a WordPress file that enables communication between WordPress and other systems (e.g., publishing from mobile apps, trackbacks, pingbacks). While once vital, its functionality has largely been replaced by the REST API, and it’s a common target for brute-force attacks and DDoS attacks.

What is XML-RPC?

It’s an API that allows remote interaction with your WordPress site.

Why Disable It (If Not Needed)?

• Brute-Force Attacks: Attackers can use xmlrpc.php to perform thousands of login attempts with a single request, bypassing some login attempt limits.
• DDoS Attacks: Can be exploited to launch distributed denial-of-service attacks.
• Security Vulnerabilities: Historically, XML-RPC has been a source of security exploits.

How to Fix It:

1. Check if You Need It: If you’re not using WordPress mobile apps, Jetpack (which can use XML-RPC), or other remote publishing tools, you likely don’t need it.

2. Disable via Security Plugin: Many security plugins (Wordfence, iThemes Security) offer an option to disable XML-RPC functionality. This is the easiest and safest method.

3. Disable via .htaccess (Advanced): Add the following code to your .htaccess file in the root of your WordPress installation:
   apache

   
   order deny,allow
   deny from all
   

4. Disable via Code (Advanced): Add this snippet to your theme’s functions.php file (preferably in a child theme) or a custom plugin:
   php
   add_filter(‘xmlrpc_enabled’, ‘__return_false’);

   Note: If you use Jetpack, disabling XML-RPC might break its functionality. In such cases, rely on your security plugin’s brute-force protection for XML-RPC.

Not Limiting Login Attempts

Brute-force attacks aim to gain unauthorized access by systematically trying countless combinations of usernames and passwords until the correct one is found. Without limits, an attacker could try millions of combinations per hour.

Brute-Force Attacks

These attacks are common, automated, and can quickly compromise your site if left unchecked.

How to Fix It:

1. Use a Security Plugin:

   • Wordfence: Automatically blocks IPs after a certain number of failed login attempts.
   • iThemes Security: Offers brute-force protection as a core feature.
   • Limit Login Attempts Reloaded: A dedicated plugin specifically for this purpose.
   • Install and configure one of these plugins to define the number of allowed login attempts and the lockout duration.

2. Add .htaccess Rules (Advanced):
   You can implement some basic .htaccess rules to block IPs after multiple failed attempts, but this is less dynamic and robust than a plugin. For instance, you can block specific IP addresses that are known to be malicious, or use more advanced configurations that detect and block patterns. However, a good security plugin handles this more efficiently and intelligently.
3. Hostinger’s Role: Hostinger’s WAF and server-level monitoring can also help mitigate brute-force attacks, but an application-level solution like a WordPress plugin adds crucial defense.
